Resumen del manual
The normally closed auxiliary contacts of both K55 and K56 open preventing the K57 contactor from energizing. If the combi fan is in the reduced setting 220 VAC is sent from terminal 6 on connector X11 through the normally closed auxiliary contacts of contactors K55 and K56 to the coil of contactor K57 The K57 contactor closes Sending 220 VAC through the Q57 thermal overload to the motor and the motor turns at a reduced speed. The normally closed auxiliary contacts of K57 open preventing the K55 and K56 contactors from energizing. For the first 2 minutes 220 VAC is sent from terminal 4 on connector X11 through the normally closed auxiliary contacts of contactor K5 to the K50 contactor coil K50 contactor closes and the motor turns CW The normally closed auxiliary contacts on K50 open preventing the K5 contactor from energizing. For 15 seconds the motor is de-energized and allowed to coast. For the next 2 minutes 220 VAC is sent from terminal 3 on connector X11 through the normally closed auxiliary contacts of contactor K50 to the K5 contactor coil K5 contactor closes and the motor turns CCW The normally closed auxiliary contacts on K5 open preventing the K50 contactor from energizing. NOTE: If the door switch (S7) opens by the door opening, then the fan circuit is de-energized. Then the motor will be pulsed in the opposite direction to “break” the fan. This is to stop the fan quicker for the operator. The hot air heat circuit is energized 220 VAC is sent from terminal 3 of connector X12 on the Control Board (A10) through the normally closed auxiliary contacts of K2 and K1 to the coil of Contactor K4 until the cabinet reaches the set temperature as sensed at probe B6. The contactor K4 closes and to legs of the 220 VAC is sent to the 18 KW element (E4) 220 VAC is sent from terminal 7 of connector X11 on the Control Board (A10) to the coil of Contactor K44 until the cabinet reaches the set temperature. The contactor K44 closes and the third leg of 220 VAC is sent to the 18 KW element (E4) If the reduced power option is chosen then the K44 Contactor is not energized. The steam circuit is energized 220 VAC is sent from terminal 4 of connector X12 on the Control Board (A10) to the coil of the Y3 solenoid allowing water to be thrown against the element until the bypass probe (B5) senses 183 degrees F. NOTE: If the set temperature is above 212 degrees F the hot air circuit will be energized (after the by pass probe is satisfied) until the compartment setting is reached. When the condensate box is heated to 140 degrees F at the B3 probe, 220 VAC is sent from terminal 5 of connector X12 to the condenser valve (Y1) until the temperature drops. When the timer counts to 0 or the core temp probe (B10) reaches the set amount the cycle ends. With the combi in the Hot Air mode with time on the timer, the door closed and the start switch is depressed The front display will include a lighted bar under the Hot Air symbol When the heat circuit is energized the heat symbol will be energized The cooking mode symbol will be energized. The time display will invert and begin to count down. The fan circuit is energized NOTE: If the temperature is less than 212 degrees F than fan will be pulsed on for 2 seconds every 60 seconds after the cabinet set temp (B6) If the combi fan is in the normal setting 220 VAC is sent from terminal 5 on connector X11 through the normally closed auxiliary contacts of contactor K57 to the coils of contactors K55 and K56 The K55 and K56 contactors close sending 220 VAC through the Q56 overload to the motor and the motor turns at a high speed. The normally closed auxiliary contacts of both K55 and K56 open preventing the K57 contactor from energizing. If the combi fan is in the reduced setting 220 VAC is sent from terminal 6 on connector X11 through the normally closed auxiliary contacts of contactors K55 and K56 to the coil of contactor K57 The K57 contactor closes Sending 220 VAC through the Q57 thermal overload to the motor and the motor turns at a reduced speed. The normally closed auxiliary contacts of K57 open preventing the K55 and K56 contactors from energizing. For the first 2 minutes 220 VAC is sent from terminal 4 on connector X11 through the normally closed auxiliary contacts of contactor K5 to the K50 contactor coil K50 contactor closes and the motor turns CW The normally closed auxiliary contacts on K50 open preventing the K5 contactor from energizing. For 15 seconds the motor is de-energized and allowed to coast. For the next 2 minutes 220 VAC is sent from terminal 3 on connector X11 through the normally closed auxiliary contacts of contactor K50 to the K5 contactor coil K5 contactor closes and the motor turns CCW The normally closed auxiliary contacts on K5 open preventing the K50 contactor from energizing.
